Tkinter is an inbuilt Python module mostly used to make simple GUI desktop applications. It is an open source and portable GUI library designed for using in Python scripts. So, we do not need to install Tkinter module as it comes with Python by default.
3. Data Analysis
Python is the most favored by data researchers among the various programming languages (like Java, SQL, Matlab, SAS, R, etc). It provides a popular Pandas library for data analysis.
Pandas has two important data structures, namely Series and DataFrame. It can store any type of data, like integers, floats, strings, objects, and others. DataFrame is a tabular data structure with labelled rows and columns, same as an Excel spreadsheet.
You can use Pandas to fill in missing data, reshaping, indexing, merging, slicing, and joining of datasets. It also helps to read Comma-Separated Values (CSV) files, Microsoft Excel, SQL database, and HDF5 (Hierarchical Data Format) files.
4. Machine Learning and Artificial Intelligence Applications
Python provides pre-defined packages for developing machine learning and artificial intelligence applications. It made the developer’s life easy. Some of the popular pre-defined packages provided by Python are as:
- Scikit-Learn (Popular)
- NLTK, etc.
Python provides a popular standard library named Statsmodels used for statistical analysis. We can use Statsmodels library across various fileds like economics, finance, and engineering.
It also supports many models and features, such as linear regression models, generalized linear models, discrete choice models, and functions for time series analysis. We can also use Statsmodels library along with Pandas to fit statistical models.
6. Cloud Computing
OpenStack is an open source cloud computing infrastructure software written mainly in Python. It is used to create and manage both public cloud and private cloud infrastructure. It is highly reliable, vendor independent, has inbuilt security and provides decent load balancing.
OpenStack provides a dashboard as a central unit to manage network resources, processing power, and storage at a data center.
7. Software Development
We can use Python for the software development process. It acts as a help language and can be used for fabricating control and management, testing, and so forth.
- SCons is an open source built tool written in the Python language widely used to build control.
- Buildbot and Apache Gumps are frameworks used for automating software built, test, and release processes.
- Round or Trac are frameworks written in Python for bug tracking and project management.
8. Scientific and Numeric
Python is widely useful in scientific and numeric computing. Python consists of five core scientific packages, namely SciPy library, NumPy, Jupyter, Sympy, and Matplotlib.
Most of these tools come under BSD (Berkeley Software Distribution) license. We can use these tools without any restrictions.
- We mainly used SciPy library for numerical integration and optimization.
- NumPy provides N-dimensional array objects, used to perform linear algebra, Fourier transform, and other mathematical operations.
- Jupyter offers an interactive web-based interface which can be called by browser. We also use Jupyter library to write Python programs and create embeddable plots to visualize data.
- We can use Sympy library to produce symbolic mathematics.
- Matplotlib is the oldest and most popular plotting library in Python.
9. Business Applications
We can build business applications like online E-commerce and ERP (Enterprise Resource Planning). These kinds of application need extensively, scalability and readability to solve specific business needs of an organization. Python offers all these features to build business applications.
